I have tested Windows 7 RC and just as there was more than satisfied. Now I have the ready-installed Home Premium version as custom installation (not an upgrade) and what can I say - it met my expectations. Everything goes very fast (copy files, open programs, etc.). For all of my devices the correct driver (maybe you have to install, even with the optional updates start) was automatically installed via Windows Update. Even my old HP Photosmart multifunction printer goes (the software I downloaded from the HP site itself and installed). The new Taskbar I find very convenient, just the so-called "Jump List" which opens by right-clicking on an icon can make life very. I would buy it immediately. I used to work does not regret having the reinstall, back up data and copy it back again, etc. causes. But I now have a PC of immediately responding to my inputs and is very easy to use. The only problem which I've encountered: Kaspersky 2009 can not be installed, it must be free upgrade to KIS 2010. But that was not a good idea. Kaspersky 2010 makes the PC very slowly. Now I have Norton 2010 installed (KIS 2010 before completely uninstall and restart your PC!) Now the PC is running again very beautiful fast.
A tip to the end: The search works very quickly and well, so if you take not know where something is, for example, in the Control Panel updates, simply "update" in the search box at the top right of the Control Panel to enter, or the search box completely. use the bottom of the Start menu.
